RAIL-FASTENING.

Specification of Letters Patent.

Patented Aug 25, 1908.

Application filed July 22, 1907. Serial No. 384,859.

To all whom it may concern:

Be it known that I, ALLEN NEWELL, a citizen of the United States, and aresident of Guadalajara, Mexico, have invented a new and ImprovedRail-Fastening, of which the following is a full, clear, and exactdescription.

This invention relates to fastenings.

While the invention is capable of use in many connections, it is adaptedmore particularly for use in connection with metal ties for holdingrailway rails thereon.

The object of the invention is to produce a fastening device which, ifsubjected to jars or vibrations, will operate to clamp a member such asa rail, and maintain the clamping force with the same or greaterintensity by reason of the vibration or jar to which the parts aresubjected.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and particularly set forth in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both figures.

Figure 1 is a longitudinal section taken through the end of a railwaytie to which my rail fastening is represented as applied; certain partsare shown in elevation and the rail is shown in cross section; and Fig.2 is a plan of the parts shown in Fig. 1.

Referring more particularly to the parts, 1 represents the body of therailway tie. This tie presents oppositely disposed parallel side bars 2which are connected at their ends on the lower side by a tie bar 3. Atthe end of the tie above this tie bar 3 another cross bar or bridge 4 isformed, which integrally connects the side bars 2. This bridge is formedwith a reinforcing boss 5 directly beneath the position of the rail 6,the said rail being received upon a flat seat or face 7 flush with'theupper edges of the side bars 2, as shown. The rail is disposed near theouter end of the tie, and the end of the tie beyond the rail is formedinto a massive rail support or chair 8, which fits the outline of therail as shown, and supports its outer side. Near the inner edge of therail flange the upper edges of the side bars 2 are provided with notches9.

- These notches have curved forward edges and abrupt rear edges 10, theedges 10 being disposed substantially vertically and re moved a slightdistance from the edge of the rail flange'as shown. side bars 2 areconnected by another cross bar or web 11, of angular form, as shown,presenting an upwardly projecting flange 12, the purpose of which willappear more fully hereinafter.

In the'space between the side bars 2, a clamp 13 is mounted upon a pivotbolt -14 which passes horizonta y through the tie. This pivot boltprojects at one end beyond the side of the tie, and receives a split pin15 which holds it in position, as will be readily understood. In itsconstruction, the clamp 13 consists of a hub 16, of substantiallycircular form, from the lower portion of which a horizontal too 17projects under the position of the rail as indicated. From the up perportion of the hub 16 an upwardly eX- tending jaw 18 is formed, which isprovided with an inclined clamping face 19 which is adapted to conformto the inclined position of the upper side of the rail flange when theclamp is rotated upon the pivot bolt 14. The side facesof the jaw 18near its root, that is, near its point of connection with the hub 16,

On the under side the are formed with lateral lugs 20 which conformsubstantially to the shape of the notches 9 and flt therein, asindicated in Fig. 1. In this way it will be understood that the rearfaces of the lugs lie against the abrupt faces 10 of the notches, so asto prevent any tendency of the clamp to move backwardly away from therail.

In the boss 5 a threaded opening is provided, which receives adownwardly extensible member such as a clamping screw 21, said clampingscrew having a small rounded tip or knob 22 on the head thereof,disposed on the axis of the screw as shown.

On the side of the clamp 13 remote from the rail, an outwardlyprojecting shoulder 23 is formed, in which there is mounted a downwardlyextensible member such as a set screw 24, which is also provided with arounded knob 25 on the under side thereof. This set screw 24 is disposedjust above the flange 12, and in such a position that when unscrewed thehead 24 will engage the upper edge of the flange, as indicated inFig. 1. Likewise, the clamping screw 21 is disposed just over the toe17, so that when unscrewed it will engage this toe.

In assembling the parts, the rail is placed in position against thechair 8. The clamp 13 is then laced in position by thrustin its toe 17und er the position of the rail and allowing it to descend so that thelugs seat themselves in the notches 9. The pivot bolt 14 is then placedin position and the screws 21 and 24 are unscrewed. As the screws 21 and24 are unscrewed, they produce a slight rotation of the clamp upon theaxis of the bolt 14, so that the jaw 18 is moved down and held firmly aainst the flange of the rail.

Attention is called to the fact that the action of gravity upon theseclamping screws tends to unscrew them; in other words, they aresuspended from above, and hence as the clamp mechanism is subjected tovibration,

the action of gravity upon the clamping screws tends to make them becometighter instead of looser. In this way the jar or shock incident to thepassing of trains tends not to loosen the fastening, but totighten it.In this way a very efiicient and durable fastening results.

Attention is called to the fact that the pivot bolt 14 is disposed tothe right of the j center of gravity of the clamp, so that the action ofgravity tends to assist the clamping actionof the jaw 18 upon the flangeof the rail.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

1. A fastening device having a downwardly extensible member and apivoted clamp engaging said member and having a j aw adapted to beapplied thereby.

2. A fastening devicehaving a body with oppositely disposed side bars, aclamp lying between said side bars and having lugs engaging the same, apivot bolt supporting said clamp, and a screw mounted in a verticalposition in said body and engaging said clamp to apply the same.

3. A fastening device having a body with oppositely disposed side barsand a bridge therebetween constituting a seat for the member to befastened, a clamp pivotally mounted between said side bars, and aclamping screw mounted in said'body and engaging said clamp to tightenthe same.

4. A railway tie having a seat for the rail and a chair formed thereinadapted to engage the outer side of the rail, a clamp pivoted in saidbody having a toe projecting under said seat, said clamp further havinga jaw adapted to engage the flange of said rail opposite said chair, anda screw mounted in said seat on the under side thereof and engaging-saidtoe to apply said clamp.

5. A fastening device having a body with oppositely disposed side bars,a clamp lyingbetween said side bars and pivotally supported upon saidbody, said clamp having a clamping aw and a laterally projectingshoulder, a transverse web connecting said side bars adjacent to saidshoulder, and a set screw mounted in said shoulder and bearing againstsaid web to apply said clamping jaw.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
